  • Does VMware ESX Fault Tolerance (FT) support depend on the CPU only?

    - by user71784
    I'm trying to find out whether VMware ESX 4.x Fault Tolerance (FT) is supported on a particular server and VMware's HCL is confusing me. It says that some servers with FT-supported processors (specifically the Xeon 3400 Lynnfield) do not support FT and some with almost identical specs (same chipset for instance) do support FT. Could this be a mistake on the HCL itself? To my understanding FT support is based only on the CPU. Thanks. RC

  • Bookmarking service search

    - by CChriss
    I use Diigo, but I'm looking for alternatives to it. The main feature I need (that most don't have) is the ability to search on the full page text. Diigo does this, but I was hoping there might be others out there to choose from too. If you know of one, I'd even consider locally installed programs that have this ability, but I do prefer web-based tools for this.

  • Hide non printable characters in vim

    - by knittl
    Vim shows non-printable characters prefixed with a ^ (for instance ^@ for a NUL byte). I have a column based file containing both printable and non-printable characters which is difficult to read, since each non-printable character shifts all remaining columns one character to the right. Is there a way to hide non-printable characters or simply display a placeholder char instead? I also don't mind having every character be represented by two characters.

  • Software Raid 10 corrupted superblock after dual disk failure, how do I recover it?

    - by Shoshomiga
    I have a software raid 10 with 6 x 2tb hard drives (raid 1 for /boot), ubuntu 10.04 is the os. I had a raid controller failure that put 2 drives out of sync, crashed the system and initially the os didnt boot up and went into initramfs instead, saying that drives were busy but I eventually managed to bring the raid up by stopping and assembling the drives. The os booted up and said that there were filesystem errors, I chose to ignore because it would remount the fs in read-only mode if there was a problem. Everything seemed to be working fine and the 2 drives started to rebuild, I was sure that it was a sata controller failure because I had dma errors in my log files. The os crashed soon after that with ext errors. Now its not bringing up the raid, it says that there is no superblock on /dev/sda2, even if I assemble manually with all the device names. I also did a memtest and changed the motherboard in addition to everything else. EDIT: This is my partition layout Disk /dev/sdb: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x0009c34a Device Boot Start End Blocks Id System /dev/sdb1 * 2048 511999 254976 83 Linux /dev/sdb2 512000 3904980991 1952234496 83 Linux /dev/sdb3 3904980992 3907028991 1024000 82 Linux swap / Solaris All 6 disks have the same layout, partition #1 is for raid 1 /boot, partition #2 is for raid 10 far plan, partition #3 is swap, but sda did not have swap enabled EDIT2: This is the output of mdadm --detail /dev/md1 Layout : near=1, far=2 Chunk Size : 64k UUID : a0feff55:2018f8ff:e368bf24:bd0fce41 Events : 0.3112126 Number Major Minor RaidDevice State 0 8 34 0 spare rebuilding /dev/sdc2 1 0 0 1 removed 2 8 18 2 active sync /dev/sdb2 3 8 50 3 active sync /dev/sdd2 4 0 0 4 removed 5 8 82 5 active sync /dev/sdf2 6 8 66 - spare /dev/sde2 EDIT3: I ran ddrescue and it has copied everything from sda except a single 4096 byte sector that I suspect is the raid superblock EDIT4: Here is some more info too long to fit here lshw: http://pastebin.com/2eKrh7nF mdadm --detail /dev/sd[abcdef]1 (raid1): http://pastebin.com/cgMQWerS mdadm --detail /dev/sd[abcdef]2 (raid10): http://pastebin.com/V5dtcGPF dumpe2fs of /dev/sda2 (from the ddrescue cloned drive): http://pastebin.com/sp0GYcJG I tried to recreate md1 based on this info with the command mdadm --create /dev/md1 -v --assume-clean --level=10 --raid-devices=6 --chunk=64K --layout=f2 /dev/sda2 missing /dev/sdc2 /dev/sdd2 missing /dev/sdf2 But I can't mount it, I also tried to recreate it based on my initial mdadm --detail /dev/md1 but it still doesn't mount It also warns me that /dev/sda2 is an ext2fs file system but I guess its because of ddrescue

  • UNIX command for replace files

    - by all-R
    Hi, on Mac, you know there is no 'merge files' when you command+c/command+v some folder on another one, it actually replaces it. I'm simply wondering on what UNIX is this based? Because correct me if I'm wrong, but "cp - R" DOES merge files, no? And that's what I'm doing via the Finder, copying some files and folders... thanks!

  • x86 Router Benchmarks?

    - by Kevin
    I have grow to prefer x86 based router OS's like Vyatta and pfSense over their competitors Cisco and Juniper (Well, I never really used Juniper, but still.). However, they feel "fake" to me, like "Frankenstein" routers. I think my greatest worry is that I am missing out on something by not using the main contenders. Are there any benchmarks out there that compare the main metrics (throuput, etc.) of x86 router operating systems to their proprietary counterparts?

  • How to implement a secure authentication over HTTP?

    - by Zagorax
    I know that we have HTTPS, but I would like to know if there's an algorithm/approach/strategy that grants a reasonable security level without using SSL. I have read many solution on the internet. Most of them are based on adding some time metadata to the hashes, but it needs that both server and client has the time set equal. Moreover, it seems to me that none of this solution could prevent a man in the middle attack.

  • Problems downloading Full Magento install via purely FTP on shared server

    - by optician
    I'm currently trying to download a full magneto install from a ftp server. The connection keeps failing, it seems as if there are too many files and folders to scan through? Can anyone shed any light on how to resolve this? The shared platform seems to b e a standard platform based on Plesk 8.6. As this is a shared server, there is no option for me to really do anything, apart from contact the hosting company (who have offered to zip up all the files for me, but this is not ideal)

  • Is there an online identicon creator?

    - by wonsungi
    I thought the pictures associated with our profiles were automatically generated until they were manually changed. A lot of people have these cool identicons based on their IP address. How can I get my own identicon? I am looking for an online generator. Gravator does not seem to have any options to generate identicons. Edit: I will probably accept your answer if you just tell me how you made your identicon (and it did not involve downloading/installing stuff)

Thanks.

  • Can Gitosis enforce correct user name/email?

    - by koumes21
    Gitosis is able to authenticate users based on public/private key pair. It is able to find out which user is currently committing. However, the user name and email is taken from the client's Git configuration ('git config user.name' etc.), which can be set to arbitrary values. Is there any way to associate user names and emails with their public keys and then make Gitosis uses these names and emails as the name and email of the committer?

  • Is it possible to get a list of running processes with a Cloudwatch Alarm?

    - by jtalarico
    We have an EC2 instance (Ubuntu) that has a few java-based applications and lately we're getting hit with high CPU utilization spikes that trigger one of our Cloudwatch alarms. By the time we get into the server to look at the cpu utilization, things have calmed down. What we'd love to see in one of the alarm emails is a list of running processes and their cpu utilization(%) at the time of the alarm. Is this even possible?

  • Install xenserver on iscsi target

    - by Ghassen Telmoudi
    Is is know that Xen Server is based on CentOS, and it is fact that CentOS can be installed on an ISCSI target flawlessly, but I wanted to install Xen server on an ISCSI target I couldn't find a way. I already tried the latest version of xen server 6.2, and there is no obvious way who to do the installation without a local disk. Does anybody have an idea about the subject, or did someone know how to do it? Please share your experience about this subject.
